Fix keyword cannibalization between two posts

Two posts on [yourdomain.com] are both ranking, poorly, for "[how to remove
background from a photo]": one is a 2023 post about using Photoshop, the other is a
2025 post about free online tools. GSC shows Google alternates which one it shows in
search results week to week, and neither breaks into the top 5.

POST A: [URL, publish date, word count, current ranking position]
POST B: [URL, publish date, word count, current ranking position]
POST A CONTENT SUMMARY: [paste or describe]
POST B CONTENT SUMMARY: [paste or describe]

Diagnose and fix this like someone who understands Google is confused, not just
annoyed:
1. Confirm this is true cannibalization (same intent, Google can't decide which to
   rank) rather than two posts that legitimately serve different intents but happen
   to share a keyword, e.g. "Photoshop method" vs. "free tool method" could be
   genuinely different sub-intents if the query has commercial and free-tool
   variants.
2. If it's genuine cannibalization, recommend one of three fixes based on the
   specifics given: merge into one comprehensive post and 301 the weaker one, or
   keep both but re-target one to a more specific long-tail variant (e.g. "remove
   background in Photoshop" vs. "free background remover no download"), or noindex
   the clearly weaker/thinner one.
3. If you recommend merging, specify which post's URL survives (usually the one with
   more backlinks or age, state which factor you're weighting) and draft the outline
   for the merged version combining the best sections of each.
4. If you recommend re-targeting instead, give the exact new title, H1, and meta
   description for each post so their targeting no longer overlaps, and specify the
   2-3 heading changes each needs.
5. Flag any other pages on the site that link to either post with anchor text like
   "remove image background," since those internal links are actively feeding the
   confusion and need updating regardless of which fix you choose.
